I used Shell in my 93 octane pro tuned WRX and I watched my numbers fairly religiously and I swear it ran best on Shell. Then I traded and got the M240 and noticed that on the fuel door. So…still going there when convenient. Majority of the time. Who knows…
People who say the brand doesn’t matter have simply never looked at how their cars are reacting to different brands. Shell absolutely is one of the best if not the best.
Try filling with Shell 93 then try something like Gulf 93 and watch all those timing corrections kick in.

All my cars have always ran best on shell
It’s probably all the tears of Nigerian orphans boosting the natural lubricants
Finally, a use for all the tears.
I’ve just been using them to season caviar, like a fool!
I’ve definitely seen less knock retard on shell 91. Costco 91 is close.
76 and Sinclair at the worst.
Same 123d m and m140i best mpg , performance and pops and bangs from Shell
